Torque Required while Load is Ascending in Screw Jack Solution

STEP 0: Pre-Calculation Summary

Formula Used

Torque Required while Load is Ascending = Mean Diameter of Screw/2*Load*tan(Angle of Friction+Limiting Angle of Friction)
T_asc = d_m/2*W*tan(θ+Φ)
This formula uses 1 Functions, 5 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Torque Required while Load is Ascending - (Measured in Newton Meter) - Torque Required while Load is Ascending is described as the turning effect of force on the axis of rotation. In brief, it is a moment of force. It is characterized by τ.
Mean Diameter of Screw - (Measured in Meter) - The Mean Diameter of Screw is the diameter of the imaginary co-axial cylinder that just touches the crest of an external thread or the root of an internal thread.
Load - (Measured in Newton) - Load is the instantaneous load applied perpendicular to the specimen cross-section.
Angle of Friction - (Measured in Radian) - The angle of friction is the angle of a plane to the horizontal when a body placed on the plane will just start to slide.
Limiting Angle of Friction - (Measured in Radian) - The Limiting Angle of Friction is defined as the angle which the resultant reaction (R) makes with the normal reaction (RN).

STEP 1: Convert Input(s) to Base Unit

Mean Diameter of Screw: 0.24 Meter --> 0.24 Meter No Conversion Required
Load: 1000 Newton --> 1000 Newton No Conversion Required
Angle of Friction: 75 Degree --> 1.3089969389955 Radian (Check conversion here)
Limiting Angle of Friction: 12.5 Degree --> 0.21816615649925 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_asc = d_m/2*W*tan(θ+Φ) --> 0.24/2*1000*tan(1.3089969389955+0.21816615649925)

Evaluating ... ...

T_asc = 2748.45186579357

STEP 3: Convert Result to Output's Unit

2748.45186579357 Newton Meter --> No Conversion Required

FINAL ANSWER

2748.45186579357 ≈ 2748.452 Newton Meter <-- Torque Required while Load is Ascending

(Calculation completed in 00.004 seconds)
